Re: [Kimchi-devel] [PATCH 3/4] Remove unnecessary import aliases

In order to make the code less ambiguous and more consistent, only use import aliases (i.e. 'import ... as ...') if it is needed to solve a conflict in the imported class names. For example, if there is a class named 'kimchi.model.file', the following import statement would lead to an anbiguity when trying to use the type 'file' (because of the built-in type 'file'): from kimchi.model import file One of the solutions to this conflict would be to use an alias, e.g.: from kimchi.model import file as kfile Unless it is necessary, do not use import aliases.
